International Comfort Products FBF075B12A3 Control Board
The International Comfort Products FBF075B12A3 control board is designed to control everything including the gas valve, the igniter, the flame sensor as well as the air circulator all together. Heating and cooling systems will not even run at all lest this board is accurately installed and configured. Be absolutely sure upon picking a replacement board due to differences in models and types. A matching board is supposed to have a part number that matches both the make and model of the unit you have installed.
Some clues of a weak main board
- Power to the control board needs to be reset quite frequently for everything to run again
- When turned on, there is flashing code directly on the control board
- The entire system is unwilling to run whatsoever
